--- Comment #8 from Stefan Rink <stefanrink at yahoo.com> ---
If you compile grep with gnuregex (like FreeBSD 12) it's okay.

With gnuregex; (edit grep.h to include gnuregex.h instead of gnuregex.h)
[root at SuperBSD /tmp/test]# cc -o grep *.c -lgnuregex -L/usr/local/lib
-I/usr/local/include
[root at SuperBSD /tmp/test]# time ./grep -i 'bla' /usr/ports/INDEX-13 | wc -l
    1040

real    0m0.388s
user    0m0.385s
sys     0m0.008s
[root at SuperBSD /tmp/test]# time grep -i 'bla' /usr/ports/INDEX-13 | wc -l
    1040

real    0m3.428s
user    0m3.430s
sys     0m0.008s
